please consider that the station is in one of the hottest place on earth is the sensor efficient for long period .... bcz i tried those sensor in small project but i wonder if they can handle external factors

FloOP•3/11/24, 3:54 PM

I understand. Then I guess one has to look into some sort of industrial sensors that are made for extreme conditions. I sadly dont know them by name out of my head.

Hello, Good day to everyone

, so I'm thinking of setting up a small data acquisition system on a RTOS platform, like QNX or RT-Linux. I've heard that C/C++ is commonly used for this, but I'm wondering if it's worth considering Python for everything . Should I go with "all Python" , mix it with "C" for critical parts, or just stick to C? Please I need advice on this

techielew•3/12/24, 1:57 AM

I'd say it depends on your design objectives and what you're comfortable in working in but if you need to use an RTOS and are familiar enough with C, why not just keep it small and straightforward and go with that? Any @Middleware & OS folks want to weigh in on this?

Thank you @techielew , I am actually comfortable working with C , but i just need something faster and easier to work with, with ease in debugging.

Joseph Ogbonna•3/12/24, 9:10 AM

For a solid data acquisition setup on an RTOS, go with the main stack , your C/C++. Python might not handle the real-time stuff as well. Keep it straightforward. C is quite good and you should be able to see some example files for it than Python

It has got very confused datasheet and wiring. If here someone who has a few experience with that, I will be glad, thank you.

Chimmuanya Okere•3/12/24, 9:36 PM

Currently working on the power section of my schematics design. Am using a voltage regulator of 3.3v 500mA. The total power(current) of the board at full load (when operating at full capacity) is 470mA, and the regulator has a drop out or leakage current of about 50mA.
Will it still be ok for me to use this regulator or I should change to another. But the device will not always operate at full capacity, just once in a while. Will it cause any issue on the board. @PCB & Analog @MCU, MPU & Firmware

aymen ammari•3/12/24, 10:21 PM

For butter results and the regulator won't heat up you have to add at least 25-30% that means you're consuming 450mA you should use 563mA - 585mA more is better , also it is recommended to use a heat sync with some thermal paste on it, because the heat effects regulator by time
